Abstract
An induction heating cooker includes a top plate adapted to have an object placed thereon, plural heating coils provided below a lower surface of the top plate, an inverter for supplying high-frequency power to the heating coils, a data memory, and a controller controlling the inverter. The data memory stores first and second heating coil patterns. Each of the first and second heating coil patterns defines one or more heatable regions and one or more non-heatable regions. The controller selects a heating coil pattern from the first and second coil patterns. The controller controls the inverter such that high-frequency power can be supplied to one or more first heating coils out of the plural heating coils located in the one or more heatable regions of the selected heating coil pattern. The controller controls the inverter such that high-frequency power cannot be supplied to one or more second heating coils out of the plural heating coils located in the one or more non-heatable regions of the selected heating coil pattern. This induction heating cooker can adjust at least one of the location, the size, and the number of the heatable regions for induction-heating objects in response to at least one of the location, the size, and the number of the objects to be heated, thereby heating the objects efficiently.
